Karaoke

I enjoy karakoe every once in a blue moon – but then only when people singing actually have the talent to do so. But why is it that people who are tone-deaf and have a very monotone voice insist on singing karaoke? I have one such neighbour who insists on every now and again singing karaoke from home – all I can do to drown out the monotonous drone of his voice is to turn up the volume on the radio/amplifier. Do these types of people just not understand that they’re causing noise-pollution?
